prove-sin(2x)+cos(2x)=1

prove

- sin (2 x) + cos (2 x) = 1

False

Solution steps

- sin (2 x) + cos (2 x) = 1

Show that the two sides are not equal

For

- sin (2 x) + cos (2 x) = 1

plug in

x = 1

- sin (2 \cdot 1) + cos (2 \cdot 1) = - 1.32544 \dots

- sin (2 \cdot 1) + cos (2 \cdot 1)

Refine to a decimal form

= - 1.32544 \dots

The two sides are not equal

\Rightarrow False

sin (x) (sec (x) tan (x)) = tan^{2} (x)

\frac{cos ( x ) - cos ( 3 x )}{sin ( 3 x ) - sin ( x )} = tan (2 x)

sin ((3 θ + 72)^{\circ}) = cos (4 8^{\circ})

tan (θ) + cot (θ) = \frac{1}{sin ( θ ) cos ( θ )}

sin (x) tan^{2} (x) = sec (x) tan (x) - sin (x)
